sqliteHow can I write SQLite queries?
Writing SQLite queries is relatively straightforward. The basic syntax is very similar to other SQL databases like MySQL and PostgreSQL. Here is an example query to select all records from a table called Customers
:
SELECT * FROM Customers;
The output of this query will depend on the data in the table, but will generally be a list of all the records in the table.
To narrow down the results, you can use a WHERE
clause to specify criteria. For example, to select all customers with a city
of 'New York':
SELECT * FROM Customers WHERE city = 'New York';
You can also use ORDER BY
to sort the results, and LIMIT
to limit the number of rows returned. For example, to select the first 10 customers in alphabetical order:
SELECT * FROM Customers ORDER BY name LIMIT 10;
You can also use JOIN
to combine data from multiple tables. For example, to select all customers and their orders:
SELECT * FROM Customers
JOIN Orders ON Customers.id = Orders.customer_id;
